To cil/051cmtiring/'concern Beit known that l, Gnoncn L. BLANCHARD, a citizen of the United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented certain nen' and useful improvements in Floats for Linters; and l do hereby declare the following to be a full, clear, and exact. de-4 scription of the invention, such as will enable others skilled in the art to which it appertains to malte and use the same.

T ie present invention relates to floats for linters for delinting cotton seed and has for its purpose to provide an arrangement whereby the floatgreatly assists the linter machine in removing the lint from the seed to the end of greater recovery of lint, and ob` taining a larger amount of oil from the seed.

ri further purpose of the invention is to construct a delinteriloat wherein the several part-s thereof vare simply constructed and easily assembled, or dis-assembled, and Which may be readily installed in any linting inachine without requiring any alteration in its structure.

The invention as disclosed herein is proposed as an improvement over that type of delinter float disclosed in my S. Patents, bios. `947367 and 1015724, dated January 1910 and January '23, 1912, respectively.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views z-Figure 1 is a top plan view, with part-s broken aivay and shoivnin section, of a linter; Fig. 1a is a trztnsverse sectional vieiv of the iloattalten on the line 1 1 of Fig. Fig. 2 is a longitudinal sectional vien of the float with parts removed for clearness; Fig. @eis a transverse sectional vievv taken on the line 2 2 of Fig.

l and Fig. 3 is a transverse sectional vieiv taken on the line of Fig. if.

Referring to the construction in further detail, l designates the lint-er casing or roll box, having the usual saws 2 arranged to perform their ordinary functions.

The float consists of a plurality of cylindrical sections 3 composed of emery, or other abrasive sulpistance, and which are coaxiallv assembled to provide a cylinder having a corrugated Working surface. The cylinder portions between the several corrugations a have cylindrical extensions `which,`

ivnen the several cylindery sections are assembled, provide abrasive shoulders 5, the purpose of' which will be described hereinafter.

The several cylindrical sections of the abrasive cylinder are mounted on a shaft 6 o f polygonal or circular design in cross section, and the means for securing the several cylinder sections consists of a plurality of co-aXially-assemblcd bushings `7 that are mount-ed directly on the shaft 6, and at either end said bushings are secured through the medium of a pair ofright and left threaded nuts 8 and 9, respectively. Said nuts 8 and 9 are mount-ed on the extreme ends of the shaft 6 Within the casing 1, as shown clearly in F ig. 1. Y

Each bushing 7 is constructed with annular end flanges 10 and 11, and said flanges are provided, respectively, with doivel pins lf2 and corresponding recesses 13,'adapted to have inter-engagement for locking the sev-1 eral axially-assembled bushings against relative angular movement. A pair of Wings or projections la is formed on diametrically opposite sides of each bushing, and have for their purpose to engage Within the'abrasive cylinder sections and securely mount the latter on said bushing for obvious reasons. lt will be understood, of course, that said projections or wings 14 are set Within their respective cylinder sections dnrinfv the period of formation or molding of the latter. s

A reinforcing, endless Welded ring 15 is located in each of the cylinder sections and provides a reinforcing element to prevent breakage of the Wheel when the same is subjected to excessive Wear or strain. The several cylinder sections 3 are secured to their respective bushings through the medium of a binding filler 16 Which is located Within the space provided between the bushings, bushing end flanges and the inner peripheries of the cylinder sections.

Th v binder is composed preferably of sulfur combined with rubber, or other similar substance, which will give it a very Ahard and tenacious body, to the end of overcoming the brittleness of the sulfur.

A cage surrounds the abrasive cylinder and consists of four bars 17, arranged paryallel to the shaft 6 and disposed at equal y distances apart, and suitably connected by intermediate rings 18, and end rings 19, and sald latter rings are in turn secured to the ico trunnions 20a. Intermediate the end rings 19 the bars 17 of the cage are mounted on a supporting frame 19 that is journaled on the shaft 6. (See Fig. 2a). The trunnions 20a; are journaled to rotate on the shaft 6 at either end of the casing l, in the trunnion bearings 20, and a pulley 21 is secured to one of said trunnions'for rotating the cage at a sp'eed commensurate With the speed of the abrading cylinder, in the delinting operation.

'Ihe abrading cylinder is rotated through the medium of the pulley 22 secured at one end ofthe shaft 6, as illustrated in Fig. 1.

An agitating means is carried by the cage and consists of a series of pins or fingers 23 mounted on each cage bar 17, and are disposed inwardly, each annular series fitting between each pair of the corrugations of the abrasive cylinder, or immediately around the abrasive shoulders 5; With this arrangement of agitating members and abrasive shoulders, the seeds are caused to rub against the abrasive Wheels on both sides of the corrugations 4 and against the cylindrical surfaces or annular shoulders 5, z'. e., the seed is forced to the extreme depth ofchannels formed by the `abrading surfaces. And there is the further advantage that With having the agitating pins 23 arranged at such intervals, the mass of seed is in a given time subjected to a greater working action by the abrasive Wheels than would be the case if but one series of agitating pins were used.

From the foregoing it will be obvious that the construction is simple and not liable to easily get out of repair; and further that the saw cylinder is relieved, in a great measure; of its usual work, and as a result does no; require to be sharpened at close interva s.

It is obvious that various other modifica` tions might be made in the herein described constructions Without departing from the spirit of my invention.

I claim:

1. In an abrasive cylinder for, linters, the combination of a shaft; co-axially assembled bushings mounted on the shaft and having annular channels; co-aXial ly assembled abrasive cylinder sections mounted on said .bushings; and an adhesive filling within said channels and securing the respective pairs of bushings and cylinder sections; substantially as described.

In an abrasive cylinder for linters, the combination of a shaft; co-axially assembled bushings mounted on the shaft; cdaxially assembled abrasive cylinder sections mounted on said bushings; said bushings having annular channels, and portions projecting 'into their respective abrasive cylinder sections to prevent relative movement therebetween; and adhesive fillings Within said channels and securing said bushings and cylinder sections; substantially as described.
